No you wouldn’t HAVE to. But personally, I wouldn’t spend the money to attend. Since it’s all about experiencing they day with you Mid.
Perhaps you woukd be getting together with other Mid parents? Or I could see attending classes with your Mids BFF/roomate if particularly close? But personally, I would not go. And instead attend when my Mid WAS there. On another weekend. Spend my time and money with my own. Perhaps even during a special weekend with my Mid at the exchange academy! Now THAT would be cool.
I think parents weekend is fun, but would be very much less fun without my own Mid.
I also recognize, that if you ar inquiring for this next one in September, that you went able to see he dorm or eat in King Hall during parents weekend. Bc we didn’t have one. But having done that with my oldest? You really aren’t missing much.
